  • Patent number: 11406502
    Abstract: A prosthesis for replacing a natural articular surface on a bone may have a joint facing side with an articular surface, a bone anchoring side with a bone engagement surface, and a bone engagement pad secured to at least part of the bone engagement surface. The bone engagement pad may have a transverse portion extending transverse to a length of the bone, and one or more protruding portions extending generally perpendicular to the transverse portion. The transverse portion may have a pad bone-facing surface with a first porosity level, and a pad joint-facing surface on an opposite side of the transverse portion from the pad bone-facing surface, with a second, lower porosity level. The bone engagement surface may be formed via a first manufacturing process selected from the group consisting of forging, milling, and casting. The bone engagement pad may be formed via an additive manufacturing process.

  • Publication number: 20210290410
    Abstract: A system for preparing a knee may include a marking guide with a handle and a tibial marking portion extending from the handle. The handle may have a tibial alignment feature shaped to be aligned with a first corresponding feature of a tibia and a tibial marking guide shaped to guide motion of a marking instrument to provide, on the tibia, a tibial mark that identifies a tibial location at which a tibial component is to be placed on the tibia. The marking guide may further have a femoral marking portion with a femoral alignment feature shaped to align the femoral marking portion with the tibial marking portion and/or the tibial mark, and a femoral marking guide shaped to guide motion of a marking instrument to provide, on a femur, a femoral mark that identifies a femoral location at which a femoral component is to be placed on the femur.

  • Publication number: 20210038397
    Abstract: An acetabular joint prosthesis may be designed to replace an acetabular articular surface. The prosthesis can include an acetabular cup, an augment, and an augment-securing mechanism configured to secure the augment to the cup. The mechanism can be reconfigured between an unlocked configuration in which a slider is slidable along a guide feature and a locked configuration in which the slider or guide feature is in an expanded form such that the slider is fixed in place relative to the guide feature. An unlocked configuration may include the augment-securing mechanism allowing rotation between the augment and the cup, with the augment being securable to the augment in multiple rotational positions. Also, the prosthesis may be configured to facilitate actuation between the unlocked and locked configurations, including moving an instrument to the prosthesis in an access direction that is substantially perpendicular to a rim of the cup.

  • Patent number: RE48376
    Abstract: A posterior spinal fusion system may include a plurality of cannulas that mate with cages polyaxially coupled to pedicle screws. The cannulas maintain access to the pedicle screws to facilitate percutaneous insertion of a fusion rod into engagement with the cages. Each cannula has a pair of blades that may be held together by an abutment member that at least partially encircles the blades. Each abutment member abuts the skin to define a variable subcutaneous length of the corresponding cannula. Each abutment members is also lockably removable from the corresponding blades to enable the blades to pivot with respect to the connecting element to a position in which they can be withdrawn from the connecting element. The blades of each cannula are spaced apart to provide first and second slots of each cannula, through which the fusion rod can be percutaneously inserted.
